Abstract

We examine the problem of extending a distributed loop network by adding spare nodes and links so as to make it more fault-tolerant. The optimization criterion used in finding a fault-tolerant solution is to reduce the node-degree of the overall network. This is important in practice due to the limitation on the number of links allowed per node in VLSI design. Our results indicate that the solutions obtained (numerically or analytically) are efficient, i.e., either optimal or nearly-optimal.
